Understanding the Role of Regression Testing Services and How it is Performed

What is Regression Testing Services?

Mobile applications, websites, and Softwares are updated frequently to introduce new features in software. This process of updating a software introduces new bugs in software. Regression testing services make sure that the new software works the way it is intended to work without any glitches or errors.

Before delivering a new version of a software, old test cases run on a new version to assure that old features are working fine even after a software update. 

Techniques Utilized by Regression Testing Services :

Retest All

It is one of the practices of this testing in which each test in an existing test suite re-executed. It is expensive as it needs plenty of time as well as resources.

Regression Test Preference

Rather than re-executing a complete test suite, it is more useful to choose the part of the test suite to run –

• Test chosen cases described as
• Reusable Test samples
• Obsolete Test samples
• Reusable Test samples used in succeeding Regression cycles. Obsolete Test samples not used in succeeding cycles.
• Prioritization of Test examples

To prioritize test situations depending on the business, significant, and frequency used functionalists. Choice of test cases based on priority will significantly decrease the regression test set.

How does Regression Testing Work?

This testing is done manually. Though, as application development demands time, more and more functionality retains expanding the scope of regression; hence, this testing is conducted in an automated way.

While developing a test suite for regression, take the following into consideration–

• Automate all the test proceedings of a test set.
• Renew the regression suite when needed like if any new defect which not covered in a test case found, update test case for that matter in a test suite. Conduct testing for a bug and reveal next time.
• Accomplish regression test cases, whenever modifications made in code, implement bug fixing, new functionality added, and also an improvement to existing functionality done.
• Create a test performance report which comprises pass/fails status of completed test cases.

Advantages of Regression Testing :

• Change in specifications and code altered according to the specification.
• New characteristic added to the software.
• Bug fixing.
• Fix the Performance issues.

Why Regression Testing Matters?

New Functionality – It enables adaptability with old and new code whenever new features are added.

Functionality Revision – It changes the existing functionality and checks if the feature updated or eliminated without creating any disturbance to the functionality.

Integration – It assures perfect integration with a different product.

Bug Fixing – Bug fixing needs modifying the source code done by Regression Testing.

Improved Quality – It increases the quality of the product for high-quality Assurance check.

How to Adopt Regression Testing?

The following circumstances needed to be taken into consideration–

• Analyze modifications made to the software.
• Analyze and discover what elements of software might be affected.
• List a time to test.
• Regression Testing Tools

Manual Regression testing wastes time and cost. Automated tested is being adopted by testers globally to save time and cost. 

For this, some tools are mentioned as follows –

Selenium – It is a free tool used for automating web apps. Selenium also used for browser-based Regression Testing.

Quick Test Professional – HP QuickTest Professional, is automated software created to automate functional and regression test cases. It presents the performance of Vb Script language for automation.
